Zinc and Nickel Coating Magnet in Hardness, Life and Price The most commonly used coatings for NdFeB magnets are galvanized and nickel-plated. They have obvious differences in appearance, corrosion resistance, service life, price, etc. The following are the key points. Polishing difference: Nickel plating is superior to galvanizing in polishing, and the appearance is brighter. [...]
Sintered Nd-Fe-B Magnet - The Best Way To Identify Quality The sintered Nd-Fe-B Neodymium magnet is one of the essential materials in pushing the progression of modern technology and the development of our society. Its applications widely cover most areas we encounter: hard drives, electric cars, industrial permanent magnetic devices, and consumer products such as [...]
NdFeB Grade N38H Magnetic Performance Thermal performance Demagnetization curve introduction There are many grades of neodymium magnets. For details, see the performance grade table of sintered neodymium iron boron magnets. Today we mainly introduce the 38H performance grade, including its magnetic performance, thermal performance, and demagnetization curve. I hope it will be helpful to those [...]
N35H-52H Performance Arc Magnet Manufacturing Customization N35h-52h performance arc magnet refers to the rare earth NdFeB magnetic tile with maximum temperature resistance of 120 ℃. It is mainly used in various DC motors. Our company can make NdFeB tile shaped magnetic steel products with different sizes, radians, coatings and temperature resistance according to the customer's [...]
Ce Substitution Level in NdFeB Magnets Ce substitution level in Nd-Fe-B magnets has been significantly increased via the binary main phase (BMP) approach, i.e. sintering the mixture of Ce-free and Ce-containing RE 2 Fe 14 B (RE, rare earth) powders. REFe 2 phase that forms in the high Ce-containing Nd-Ce-Fe-B magnets has been considered to [...]
Advantages Of HSMAG Magnetic Separator Magnetic separator is the most widely used beneficiation equipment in ore beneficiation production. It can also be used for iron removal operations in resource recovery, coal, non-metallic minerals, building materials, chemistry and other industries. It is used in hematite beneficiation processes. The removal of iron powder in the mine is [...]
Magnetic Speaker Systems Speakers have been utilising permanent magnets since 1930 and in the last 87 years the core technology has remained largely unchanged. However, with the advent of new materials and ever increasing strength of Neodymium magnets the speaker is constantly been re-invented. None more striking than the B&W Nautilus, now superseded in terms [...]
Some Introduction About Speaker Magnets Speakers are a type of transducer which can transfer the electric signal to the acoustic signal. The sound quality of the speaker is largely depended on the speaker magnets. Speakers can be classified to internal magnetic type and external magnetic type according to the magnetic circuit structure. Speakers also can [...]
HSMAG offers Extruded Neodymium Magnets for Brushless DC Motors HSMAG is uniquely positioned to offer solutions to the challenges of motor design with extruded neodymium magnets for brushless DC motors. One of the challenges in motor design is obtaining magnet prototypes to prove out your design. Once the design reaches prototype stage, the next challenge [...]
Extruded Neodymium Magnets for Brushless DC Motors Available to replace individual arc segments or slabs with multipole ring magnet, extruded neodymium magnets for brushless DC motors come in different sizes. Magnets are made by extruding bonded neodymium compound through die with established ODs and IDs. With isotropic material characteristics, final magnet can be magnetized to [...]
Neodymium Iron Boron Multipole Magnet NdFeB magnets have a higher Maximum Energy Product, (BH)max, than Sm-Co magnets. (BH) max of Nd-Fe-B can easily reach 30 MGOe and even goes up to 48 MGOe. Nd-Fe-B magnets can replace Sm-Co magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade. The temperature stability [...]
Neodymium Magnet Plating & Coating Neodymium magnets are much more susceptible to corrosion than Ceramic, Samarium Cobalt and Alnico, and would need to be coated and protected, particularly in harsh settings. They can be easily oxidized if exposed to air and moisture in atmosphere, and would become structurally vulnerable leading to breakage. To prevent this, [...]
Hall Effect Sensor Magnets for Organic Light-Emitting Diode (OLED) Deposition Apparatus, Permanent Magnets for Organic Light-Emitting Diode (OLED) Deposition Apparatus - OLED Deposition Apparatus Magnets An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric [...]
Ultra-Precise Magnetic Balancing Improves Performance, Magnetic Rotor with Mechanical and Magnetic Balancing - Generator Magnet - Power Generation Industry We were approached by a company to supply a magnetic rotor assembly for a generator application. The high speed rotor would be used for multi-phase voltage generation. The power electronics would be simple to keep costs [...]
Protective Coatings Surface Finish for Neodymium Magnets A Neodymium magnet does not corrode and will retain its performance theoretically forever in dry environment (if not subjected to excessive heat, radiation or strong external magnetic fields). However, if it is placed in a wet environment, the result may be the opposite. The within-structure Iron [...]
